barn b area 1 b = 10−28 m2
bar bar pressure 1 bar = 105 Pa
millibar mbar pressure 1 mbar = 1 hPa = 100 Pa
atmosphere atm pressure 1 atm = 1013.25 mbar = 1013.25 hPa = 101,325 Pa exactly (commonly used in atmospheric meteorology, in oceanography and for pressures within liquids, or in the industry for pressures within containers of liquefied gas)

Famous quotes containing the words common, units, officially and/or sanctioned:

    The common curse of mankind, folly and ignorance, be thine in great revenue!
    William Shakespeare (1564–1616)

    Even in harmonious families there is this double life: the group life, which is the one we can observe in our neighbour’s household, and, underneath, another—secret and passionate and intense—which is the real life that stamps the faces and gives character to the voices of our friends. Always in his mind each member of these social units is escaping, running away, trying to break the net which circumstances and his own affections have woven about him.
    Willa Cather (1873–1947)

    We who officially value freedom of speech above life itself seem to have nothing to talk about but the weather.
    Barbara Ehrenreich (b. 1941)

    The love of fame is almost another name for the love of excellence; or it is the ambition to attain the highest excellence, sanctioned by the highest authority, that of time.
    William Hazlitt (1778–1830)
